Abstract
The stress structure that subtracts that the invention provides a kind of catalyst basket have employed S shape structure due to the support ring cross-section of catalyst gauze, the thermal stress that catalytic reaction produces can be reduced significantly, in addition inverted U-shaped is adopted at catalytic basket sidewall, create a further reduction the impact of thermal stress on catalytic basket, the resistance to stress ability of catalytic basket can be greatly provided, considerably increase the service life of catalytic basket, reduce the cost of catalytic production significantly, there is very large economic benefit.
Description
Technical field
What the present invention relates to a kind of catalyst basket subtracts stress structure, belongs to technical field of chemical.
Background technology
In the reaction of catalyst furnace, temperature generally reaches more than 800 degree, at such high temperatures, the catalyst basket of bearing catalyst and catalysis net often bears very large thermal stress, cause the support section of the catalysis net of catalytic basket and sidewall to produce distortion even to rupture, have to change, add production cost.And the support section of the catalysis net of existing catalytic basket and sidewall adopt linear pattern result mostly, effectively can not eliminate the thermal stress that catalytic reaction produces, cause the service life shortening catalytic basket, make production cost increase.Therefore, be necessary that a kind of catalytic basket that better can reduce catalytic reaction thermal stress of design subtracts stress structure.
Summary of the invention
What the present invention relates to a kind of catalyst basket subtracts stress structure, belongs to catalytic unit field.
For the deficiency of above-mentioned technology, the invention provides a kind of significantly can reduce a kind of catalyst basket of catalytic reaction thermal stress subtract stress structure.
The present invention adopts following technical measures to realize goal of the invention:
Catalyst basket subtract a stress structure, it is characterized in that: the support ring cross-section of catalyst gauze is S shape structure.
Preferred:
The sidewall sections of the catalytic basket be connected with catalyst furnace housing is inverted U-shaped, can teaching display stand absorbing thermal expansion. ensure that catalyst basket is in the optimum state of level;
The top material of described inverted U-shaped is steel pipe;
The steel plate annulus being welded in inwall is provided with in described inverted U-shaped;
The steel plate being welded in junction inwall is provided with in described inverted U-shaped and catalyst furnace housing junction;
Beneficial effect: the support ring cross-section due to catalyst gauze have employed S shape structure, the thermal stress that catalytic reaction produces can be reduced significantly, in addition inverted U-shaped is adopted at catalytic basket sidewall, create a further reduction the impact of thermal stress on catalytic basket, the resistance to stress ability of catalytic basket can be greatly provided, considerably increase the service life of catalytic basket, reduce the cost of catalytic production significantly, there is very large economic benefit.

Detailed description of the invention
Composition graphs 1, Fig. 2, illustrate embodiments of the present invention:
For the deficiency of above-mentioned technology, the invention provides a kind of significantly can reduce a kind of catalyst basket of catalytic reaction thermal stress subtract stress structure.
The present invention adopts following technical measures to realize goal of the invention:
Catalyst basket subtract a stress structure, it is characterized in that: support annulus 1 cross section of catalyst gauze 6 is S shape structure, very easily produces the place of thermal stress at catalytic basket, adopt said structure, greatly can reduce the impact of thermal stress on catalytic basket.
Preferably, the sidewall sections of the catalytic basket be connected with catalyst furnace housing 5 is inverted U-shaped 2, can teaching display stand absorbing thermal expansion. ensure that catalyst basket is in the optimum state of level.
Preferably, the top material of described inverted U-shaped 2 is steel pipe, and steel pipe is stronger than the resistance to stress ability of solid steel.
Preferably, be provided with the steel plate annulus being welded in inwall in described inverted U-shaped, increase the intensity of distortion junction, improve resistance to stress ability.
Preferably, be provided with in described inverted U-shaped and catalyst furnace housing junction the steel plate being welded in junction inwall, increase the bonding strength of sidewall and burner housing, improve resistance to stress ability.
More than show and describe general principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
